Ralovera hormone pill

Hi, so i have the implanon rod in, and since i got it in i have had non-stop bleeding. So i went to the doctor who prescribed me ralovera. He explained that it helps to regulate your period so it happens at the same time every cycle for the same period of time. Anybody been taking this and have any advice? Any symptoms? Has it worked well for you? 
Also, it says to take it on the 16th day of your cycle- i dont know when that is because ive been bleeding for ages now.. Do i just take it whenever?
